1-5 Installing an Expansion Card
Read the following guidelines before you begin to install an expansion card:
•
Make sure the motherboard supports the expansion card. Carefully read the manual that came
with your expansion card.
•
Always turn off the computer and unplug the power cord from the power outlet before installing an
expansion card to prevent hardware damage.
1-6 Back Panel Connectors
(Note) The DVI-D port does not support D-Sub connection by adapter.
USB 2.0/1.1 Port
The USB port supports the USB 2.0/1.1 specification. Use this port for USB devices.
PS/2 Keyboard/Mouse Port
Use this port to connect a PS/2 mouse or keyboard.
D-Sub Port
The D-Sub port supports a 15-pin D-Sub connector and supports a maximum resolution of 1920x1200
(the actual resolutions supported depend on the monitor being used). Connect a monitor that supports
D-Sub connection to this port.
DVI-D Port
(Note)
The DVI-D port conforms to the DVI-D specification and supports a maximum resolution of 1920x1200
(the actual resolutions supported depend on the monitor being used). Connect a monitor that supports
DVI-D connection to this port.
Optical S/PDIF Out Connector
This connector provides digital audio out to an external audio system that supports digital optical audio.
Before using this feature, ensure that your audio system provides an optical digital audio in connector.
Dual Channel Memory Configuration
This motherboard provides two DDR3 memory sockets and supports Dual Channel Technology. After the memory
is installed, the BIOS will automatically detect the specifications and capacity of the memory. Enabling Dual
Channel memory mode will double the original memory bandwidth.
The two DDR3 memory sockets are divided into two channels and each channel has one memory socket as
following:
Channel A: DDR3_1
Channel B: DDR3_2
Due to CPU limitations, read the following guidelines before installing the memory in Dual Channel mode.
1. Dual Channel mode cannot be enabled if only one DDR3 memory module is installed.
2. When enabling Dual Channel mode with two memory modules, it is recommended that memory of
the same capacity, brand, speed, and chips be used for optimum performance.
•
When removing the cable connected to a back panel connector, first remove the cable from your
device and then remove it from the motherboard.
•
When removing the cable, pull it straight out from the connector. Do not rock it side to side to prevent
an electrical short inside the cable connector.
